This article presents the results of a questionnaire survey sent to a sample of automobile manufacturers in the United States and Japan (including Japanese-managed plants in the United States) during the spring of 1990. The data support observations that Japanese and U.S. practices tend to differ in key areas and Japanese suppliers perform better in dimensions such as quality (defects) and prices (meeting targets, reducing prices over time); and that Japanese-managed auto plants established in the United States have, in general, adopted Japanese practices and receive extremely high levels of quality from Japanese as well as U.S. suppliers. These findings provide evidence that Japanese practices and performance levels are transferable outside Japan and suggest that considerable improvements are possible for U.S. suppliers supplying U.S. auto plants. In addition, the survey indicates that U.S. firms have adopted at least some practices traditionally associated with Japanese firms, apparently reflecting some convergence toward Japanese practices and higher performance levels in supplier management.  相似文献

Whilst the local multiplier impacts of the annual operation of universities has been the subject of intensive research, the economic impacts of capital construction projects have been almost completely ignored. This paper presents the results of detailed analysis of capital projects at Lancaster University in 1993-The reasons for the radically different annual operation and construction multipliers estimated in the Lancaster study are examined. Despite the smaller size of construction multipliers it is argued that it is a serious mistake to estimate local construction multipliers by making simplifying assumptions on the size of the key parameters in the multiplier equations.  相似文献

In this paper we will discuss some peculiarities of the Nash equilibrium which are at odds with its standard applications: (a) the underlying dynamic interpretation, (b) the incentive independency if equilibria are mixed, and (c) the unprofitability if equilibrium and maximin are mixed and the game is 2-by-2. Maximin is proposed as an alternative solution concept in “relevant situations”.  相似文献

Around the mid-1980s, Indonesia's protectionist regime supported an industrial structure in which industries were mainly oriented towards producing for the domestic market. Since then, trade policies have shifted to a more outward-looking strategy, stimulating the growth and diversification of non-oil manufactured exports. This paper attempts to quantify the nominal and effective rates of protection resulting from trade policies at the end of the 1980s. After an introduction in which the 1989 trade policies are discussed, estimates of nominal and effective rates of protection are presented. It is shown that though the level of protection has declined since 1987, it still varies widely across economic sectors. Furthermore, despite the more open trade strategy, the paper's findings show that the trade regime remains biased against exports. Finally, by examining some trade policy issues, the paper presents further ways of rationalising the structure of protection in Indonesia's industrial sector.  相似文献

The UK will introduce in 2004 a system of tradable permits for the landfill of municipal waste, in response to an EU directive setting limits on such activity. Tradable permits are becoming an increasingly popular method of dealing with some environmental issues — for example, sulphur dioxide (SO2) emissions in the USA. This paper describes the background to the landfill proposals and provides an analysis of how the permit system might work. Estimates are made of the possible savings in compliance costs of a permit system compared with a conventional ‘command–and–control’ approach. These estimates are subject to a considerable degree of uncertainty, related to factors discussed in the paper.  相似文献

Optimal investment rules are developed for a producer agency investing in domestic-market generic advertising, export market promotion, and cost-of-production-reducing research. These rules are derived assuming either maximization of producers' surplus or social surplus. The form of the optimality rules differs according to which objective is pursued. Fixed producer agency budgets are also allowed by incorporating a constraint limiting total expenditure on the three activities. Addition of such a constraint substantially alters the structure of the optimal investment rules. Differences in these rules highlight the importance of accounting for the financing mechanism when modeling optimal checkoff fund investment decisions. Optimality rules are simulated using data for the Canadian beef sector. Results suggest historic underinvestment in domestic-market generic advertising but overinvestment in export market promotion. Sensitivity of simulation results underscores the difficulty in assessing optimality of historic producer investment in cost-of-production-reducing research.  相似文献

Summary In The Netherlands public debt management is in the hands of the budgetary policy-maker, whose recourse to the capital market can exceed or fall short of the total borrowing requirement in order to absorb or create liquidity. The conduct of that policy since the early 1960's is analyzed in this paper, emphasizing the importance of medium-term control over the public finances as a prerequisite for the ability of debt management to make a flexible contribution to monetary policy. During the 1960's this condition was satisfied and debt management followed a stable countercyclical pattern which, however, was abandoned after the early 1970's as the public finances swung into substantial disequilibrium.The author thanks J. Boughton, L. Bovenberg, D. Hendry, P. Masson, J. Muellbauer, and the referees for comments on earlier versions. However, the views expressed are his alone and do not necessarily represent those of the International Monetary Fund.  相似文献
